I am sure I said Iran but go check; either way IRAN does not need to enrich uranium.<quoted text>
I also said, but aparently you intentionally left out, was that 20% enriched uranium can be used for a crude weapon but that most nuclear weapons used 85% enriched uranium.
BTW, there was a article last year in Foreign Affairs (I doubt very much you've ever read it much less heard of it) by Kenneth Waltz on why a nuclear armed Iran could actually bring more stability to the Middle East.
Still not following your logic on why they need to continue to enrich uranium given it is not currently necessary. This leaves the international community wondering what is going on-for good reason.
One professor's opinion is not what international policies should be based on- even the UN agrees that nuclear proliferation needs curtailed.
